Definitions

  • This invention relates to fire control apparatus and methods for gas operated firearms and particularly to improved apparatus and methods in and for firearm platforms such as the gas operated AR-15, AR-10, M-16, firearms platforms and including light, medium, or heavy machine guns and other gas operated firearms.
  • Gas operated firearms are of both the direct gas impingement type of the gas driven piston type.
  • gas operated firearms of the AR-15, AR-10 or M-16 platforms or the like include a receiver, a barrel, a bolt carried by a bolt carrier in the receiver and a "gas block" mounted on the barrel.
  • the barrel is ported to the gas block and in one form of gas operated firearm, a gas tube extends rearwardly from the gas block toward the receiver and the bolt carrier. Gas pressure exits from the tube for operating the firearm through the transmission of a gas impulse, from the combustion of the cartridge, to the bolt carrier to cycle it and the bolt.
  • gas pressure ported from the barrel drives a rearwardly extending piston which engages the bolt carrier to cycle the firearm.
  • the barrel is secured to the receiver by a barrel nut engaging a barrel flange and threaded to the receiver.
  • a muzzle brake, flash hider or other barrel end device is typically mounted onto the muzzle end of the barrel. The outer parameters of these items do not permit installation of the barrel nut after these items are installed.
  • the barrel is first fitted to the receiver and secured thereon by the threaded barrel nut which is passed over the barrel.
  • the gas tube, gas block, any front sight and any barrel end device is then assembled with the front end of the gas tube being pinned into the gas block.
  • the gas block is pinned in position on the barrel.
  • the structure and outside dimensions of the gas block in particular requires the barrel nut to be applied over the barrel before the gas block or the other components, such as any muzzle end device like a flash hider or muzzle brake, are fitted to the barrel.
  • the internal diameter of the barrel nut is insufficient to allow the nut to be passed over the barrel and over the typically bulky gas block or muzzle end devices.
  • a barrel for a gas operated firearm wherein a gas block is formed integrally with the barrel, all as one piece.
  • a gas block is formed integrally with the barrel, all as one piece.
  • the gas block dimensions can be substantially reduced as compared to traditional, prior separate gas blocks.
  • the gas tube or piston receiving bore in the gas block is more closely oriented to the adjacent barrel surface so the overall outer dimensions of the integral gas block are minimal.
  • a barrel nut for holding the barrel to a firearm receiver has an inner dimension operatively larger than the outer dimensions of the integral gas block. In this fashion, the barrel nut can be applied along the barrel to its rear end and over the integral gas block; its application thus is not required to precede gas block assembly and alignment.
  • a muzzle-end device such as a flash hider or muzzle brake can be integrally formed as part of the barrel. The outside dimension of such a device being within the internal clearances of the barrel nut, which can slide thereover.
  • the entire barrel and integral gas block, together with an integral muzzle device all can be positioned for assembly to the receiver before the barrel nut is moved along and positioned on the barrel.
  • the barrel with barrel nut is positioned on the receiver.
  • the gas tube is then applied by extending into the receiver, then outwardly into the bore of the gas block where it is secured by a threaded pin screwed transversely through the block and through a transverse bore in the tube end, oriented transversely to the tube bore.
  • no barrel-torquing pin driving force is necessary for tube or gas block securement.
  • a piston is inserted into the gas block bore.
  • Another gas block bore extends from the barrel through the block and is aligned onto a barrel-facing bore or opening in the tube for gas passage to the receiver and by the gas tube positioning pin.
  • a screw is inserted through the block and the tube with a valve end adjustably seated in the gas block or barrel part for adjustment of the gas passage and operational energy for cycling the firearm.
  • Gas block and muzzle devices can be formed integrally with the barrel, eliminating separate manufacture, separate assembly, separate alignment of the block on the barrel, and torquing of the barrel by any block pin driving force.

  • FIG. 1 A firearm 10, such as an AR-15, AR-10 or other similar platform is shown.
  • Firearm 10 includes a traditional upper receiver 12 (shown with a mil. spec, picatinny rail), and, according to the invention, a barrel 14 provided with an integral gas block 16 formed monolithically with and as an integral part of barrel 14.
  • barrel 14 and gas block 16 consist of a single part.
  • Gas block 16, being an integral part of barrel 14, does not require the extra thickness for strength as would a separate add-on gas block.
  • gas block 16 is of significantly reduced, radially extending size.
  • a barrel nut 18 is internally threaded (not shown) for operative engagement with receiver 12 at externally threaded receiver extension 12a, to secure barrel 14 thereon, via flange 14a.
  • This cooperation is best illustrated in Figs. 8 and 9 where barrel 14 has a rearwardly directed extension ring 20, provided with a retaining flange 14a and an extension ring pin 24.
  • pin 24 fits into slot 26 in receiver extension 12a positions barrel 14 with respect to receiver 12 and prevents angular movement between barrel 14 and receiver 12.
  • Barrel nut 18 is provided with threaded holes 18a for attachment of components, such as hand guards or the like.
  • barrel 14 has a threaded end 28 for a variety of muzzle devices or the barrel may be fitted with an integral muzzle device, such as a flash hider, brake or other muzzle device 30 (Fig. 9) as will be herein appreciated.
  • an integral muzzle device such as a flash hider, brake or other muzzle device 30 (Fig. 9) as will be herein appreciated.
  • Prior integral muzzle-end devices as well as barrels having enlarged outer diameters at their forward end are significantly limited by the internal diameters of the prior, separately filled gas blocks.
  • firearm 10 is provided with a gas tube 32 extending from gas block 16 rearwardly into receiver 12. Gas transmitted into receiver 12 functions to cycle the bolt 34 of the firearm 10 in a well-known manner.
  • FIGs. 2-5 in a variety of views, illustrate structure of the invention at the area of the gas block 16 and forward end 36 of gas tube 32.
  • forward end 36 of tube 32 is blocked off as shown so the open interior gas passage 38 of tube 32 is closed off at end 36.
  • block 16 is herein referred to as integral with barrel 14, the combined integral barrel and gas block will also sometimes be referred to herein as the monobloc barrel for clarity.
  • block 16 has an integral, tube receiving bore 40 therein.
  • Bore 40 is generally parallel to bore 42 of barrel 14 (Fig. 2).
  • Gas tube 32 is inserted into bore 40 for operative communication with bore 42.
  • a gas passage 44 is provided in barrel 14, block 16, transverse to barrel bore 42, bore 40 in monobloc 16 and tube 32, where an opening 46 in tube 32 communicates gas passage 38 with passage 44 at bore 24.
  • gas at pressure in bore 42 passes through passage 44, opening 46 and passage 38 rearwardly to receiver 12.
  • passage 44 may be drilled through block 16 as shown in Figs. 2-4 at bore 44a, for example.
  • gas tube positioning pin 48 extends through block 16 and across the closed end 36 of tube 32. Pin 48 is threaded at 50 for securing pin 48 in block 16 and tube 32 in alignment in block 16. Pin 48 can be i nserted in block 16 through tube 32 only when tube 32 is properly aligned in gas block bore 40 so its opening 46 is indexed with passage 44 in block 16.
  • pin receiving hole 52 is provided in tube 32 transversely and at 90° extension with respect to opening 46. Only when tube 52 is rotated to align opening 46 with gas passage 44 can pin 48 be inserted across tube 32 and block 16 as shown.
  • the outer surface 54 of barrel 14 at block 16 is flat sided, or may be rounded as desired.
  • FIG. 5 An optional feature of the invention is illustrated in Fig. 5 (like parts to the foregoing bearing like numbers).
  • a further transverse bore 60 is provided in block 16, and a gas valve or gas adjusting screw 62 is threaded therein. Only a portion of block 16 is shown for clarity. Screw 62 has a valve end 64 extending into passage 44 for adjusting the effective flow area of passage 44 to adjust the gas flowing through opening 46 to passage 38 of tube 32.
  • the gas impulse thus transmitted to receiver 12 for cycling the firearm can be thus be adjusted to accommodate operating pressure variation as might be required for certain muzzle devices as noted herein.
  • a gas adjusting screw could be inserted from above through bore 44a and an additional opening in tube 32 to seat at opening 46.
  • block 16 of barrel 14, being integral therewith can be forward with only a very low extension above the normal outside diameter of barrel 14. This allows bore 40 therein to be held very closely to barrel 14, resulting in a very close final spacing of tube 32 to barrel 14.
  • this integral block structure extends only minimally above barrel 14 and nut 18 can easily be slipped over block 16 as it is positioned in assembly a the rear end of barrel 14 to secure the barrel to receiver 12.
  • This construction has a major impact and presents significant improvement over prior assemblies where the barrel nut must be slipped over the barrel before the gas block and any muzzle devices are applied.
  • Such prior structures thus require an assembly process where the later-added gas block must be applied only after barrel nut passage and typically after the barrel nut is rotated to secure the barrel to the receiver.
  • This prior process thus typically requires appropriate fixtures and tools to hold the barrel, and/or receiver for gas block alignment, and then against torquing as the prior block positioning pin is driven through the block and across the barrel. This is significant then, not only in the prior assembly process, but in later field repair or replacement of the gas tube.
  • the gas block is integral with the barrel, all passages therein are preformed as the barrel is formed. There is no later alignment of a separately provided gas block, no receiver or barrel holding fixtures are necessary for that alignment, and no torquing of the barrel respecting the gas block or receiver when any driven block position pin is applied.
  • nut 18 has an internal diameter or opening large enough to permit its movement over barrel 14 and block 16, such as illustrated in Fig. 6.
  • nut 18 is offset as it passes over block 16 of barrel 14.
  • Internal diameter surface 18b is sufficient to permit nut 18 to pass over the outer portions of integral gas block 16 as illustrated.
  • the nut 18 is concentrically oriented to engage barrel flange 14a and hold the barrel in place on the receiver 12.
  • nut 18 is provided with a plurality of circumferentially spaced slots 70 to accommodate close passage of gas tube 32 at a variety of angular positions to accommodate desire torque of nut 18 holding barrel 14 to receiver 12.
  • a further relief 80 is provided in barrel 14, under and preferably along and beyond the extent of integral gas block 16 as shown.
  • such relief in the area of block 16 allows further clearance for nut 18 over the block 16 as it is moved along that portion of barrel 14 during assembly.
  • the circular arrow at the right end of the barrel proximate the muzzle illustrates the barrel is rotated 180° in use, and as shown in Fig. 8, for example.
  • the invention provides not only improved structure and assembly process but has the advantage of greatly simplifying and speeding filed expedient gas tube replacement.
  • the invention greatly simplifies gas tube replacement.
  • the receiver bolt is retracted and held rearwardly.
  • the threaded gas tube positioning pin is unscrewed, freeing the tube. It is moved rearwardly, out of bore 40 of block 16, and then forwardly, clearing receiver 12.
  • a new gas tube is inserted into the receiver, rotated as necessary and slid forwardly into bore 40.
  • Pin 48 is then inserted, orienting the tube and opening 46 to bore 44.
